Optimizing Diet and Physical Activity to Reduce Overweight and Obesity in Licensed Taxi and For-Hire Vehicle Drivers

What this Trial Is About

Researchers are evaluating a lifestyle intervention to address overweight and obesity among licensed taxi and for-hire vehicle FHV drivers, a diverse and underserved group facing high rates of obesity and related health challenges. This study uses a hybrid effectiveness-implementation design to test four behavior change components based on Social Cognitive Theory. The goal is to identify which components most effectively and cost-efficiently promote weight loss and to prepare the intervention for broad use. Participants are randomly assigned to one of eight groups combining four behavioral components in-person individualized diet and exercise counseling, thrice-weekly diet and physical activity text messages, weekly telephone support, and self-monitoring tools for diet and weight. The study includes surveys, interviews, focus groups, and ongoing support delivered in person and virtually. Data such as step counts are tracked via participant devices or provided pedometers. Participants are involved for up to 12 months, during which body weight and cost-effectiveness of intervention components are measured. The process evaluation questionnaire assesses feasibility throughout the study. Follow-ups include phone surveys and data uploads to track progress. The study monitors weight changes, intervention costs, and participant engagement to inform future implementation.
